On February 12, 2022, the ANTARES neutrino telescope (Astronomy with a Neutrino Telescope and Abyss environmental RESearch) put an end to its data taking started in 2007. During 15 years, thousands of neutrinos, precious elusive particles witnesses of the cataclysmic phenomena of the Universe, were detected at 2500 m in the Mediterranean abyss.

The discovery of a new type of gravitational wave
Using a range of detectors developed with the participation of the CEA, physicists at CEA-Irfu have scrutinized the region from which the gravitational wave was detected on August 17, 2017 by LIGO-VIRGO facilities. Unlike the four previous detections of waves of the same type discovered since 2015, this new vibration of space, called GW170817, is of different origin. It does not result from the fusion of two black holes but of two densest known stars, the neutron stars.

It has now been more than two years that Antares1, the underwater telescope installed in the depths of the abyssal plains 2500 m under the Mediterranean, is scanning the skies through the Earth in search of neutrinos. Over a thousand of them have already been observed until today, making it possible to establish the first views of the heavens to search for high-energy cosmic neutrinos, particles that may be able to teach us more about the most violent phenomena in the Universe.

Searching cosmic neutrinos
The last two lines of the ANTARES detector were connected and powered at a depth of 2500 m on the Mediterranean seabed during the night of May 30, 2008. This brings the number of lines to twelve and completes the construction phase of the largest underwater neutrino telescope ever built. The lines were immersed a few weeks earlier, close to the other lines that have been tracking cosmic neutrinos since 2006. These particles may be able to tell us more about the most violent phenomena in the Universe.
